In this way, a constant refreshment of the base with up-to-date information has been provided. The TOCSearch simple search feature through GMC reports is implemented, which enables the exploration of GMC section by using keywords. At each moment of using TOCSearch, one can immediately start a new search or switch to advanced search tool. While exploring the database, a researcher usually performs multiple searches. In order to help the user, a tool was implemented called the "select tool". This tool enables the user to pull individual important results obtained from different searches into one place. In this way, all the data that are essential in the research are available during the further exploration. The data in the “selection” tool are easily added or removed. By using option “Feedback” the user may send a message to an administrator on different topics (site bugs, erroneous data, comments, suggestions, etc.) Preparation of reports One of the key advantages of TOCSearch is the fact that its basic data source is verified information from the reports prepared and provided by George C Marshall European Center for Security Studies. The reports are produced by special newsletter service supporting the counter-terrorism course at The George C. Marshall European Center for Security Studies, and it is created for educational purposes only. The newsletter is produced from the open-source media reports by GMC postgraduate students and verified by senior experts and counter-terrorism officers. This is the main reason why PTSS has been chosen as the main data source for TOCSearch. Besides PTSS Reports, GMC also publishes several other reports based on different open source data, such as: Department of Homeland Security Report (DHS), Terrorism Open Source Intelligence Report (TOSIR), Insurgency Literature Review (ILR) and Terrorism Literature Report (TLR). Availability of data The information in TOCSearch's database is constantly updated from GMC reports and other publicly available, open-source materials. These include electronic news archives, existing data sets, secondary source materials such as books and journals, and legal documents. The development team performs constant verification of the data by comparing it with other sources and by internal checking of the data and related records. It is also important to provide the protection of data stored in the database. In this scope, two levels of data access are implemented. The first level is named “blue key” and it is available for students and researchers in academic institutions and research centers. The “blue
